Abstract
There is no Cooper pairing in the boson-fermion model (BFM) if bosons are not condensed. There is no Bose-Einstein condensation and, consequ ently, no Cooper pairing in two-dimensional BFM. The Cooper pairing is possible in a three-dimensional BFM if and only if bosons are condens ed but can hardly be realized because of a charge-order instability.
